Source: ClinicalTrials.gov · Last updated 3 Nov 2026
Brief summary (registry, in English)
The major aim is to evaluate accuracy of 2 Continuous Glucose Monitoring Systems (CGMS) : Dexcom G6® and FreeStyle Libre® in standardized hypoxemia conditions (artificial normobaric hypoxia). Our purpose is to demonstrate the good performance and calibration of these CGM sensors in hypoxemia conditions.
